Revision 1ed91937e5cd59fdbdfa5f15f6fac132d2b21ce0 authored by Junio C Hamano on 15 December 2005, 01:30:03 UTC, committed by Junio C Hamano on 15 December 2005, 01:30:03 UTC 
GIT 0.99.9n aka 1.0rc6
 
Oh, I hate to do this but I ended up merging big usage string
cleanups from Fredrik, git-am enhancements that made a lot of
sense for non mbox users from HPA, and rebase changes (done
independently by me and Lukas) among other things, so git is
still in perpetual state of 1.0rc.  1.0 will probably be next
Wednesday, but who knows.
